"The victim was able to push away from the attacker, run home and call 911," Arlington Police Sgt. Bryan Gallagher said. "It was a very good description. The description sounded like he was a well-dressed man."

"We are taking the matter very seriously and the victim, who was not physically harmed, is being supported by family," Arlington police wrote in an email that was sent to parents.

Police released a sketch of the suspect who was described as a white man in his early 20s, with heavily gelled hair, sunglasses, a dark pea coat and khaki pants, according to the description released by police.
